Melanochromis cyaneorhabdos "maingano's" should not have any yellow on them. They are likely hybrids. They are bad for the tank, if you plan on raising any fry.
They only thing bad about them, is if you plan on raising fry, they are hybrids, which in my opinion shouldn't be sold. If you just want them for your own enjoyment, and don't distribute fry, they won't cause you anymore issues than regular johanni do.souljah77 said:So what would you suggest I do with them? I take it LFS wouldn't take them and I wouldn't want to pass it on to anyone else. What makes them so bad?
